Find LCM of 217,765,901,297,645 with Prime Factorization
3 | 217, 765, 901, 297, 645 |
3 | 217, 255, 901, 99, 215 |
5 | 217, 85, 901, 33, 215 |
17 | 217, 17, 901, 33, 43 |
217, 1, 53, 33, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 17 x 217 x 1 x 53 x 33 x 43 = 12484738035
Therefore, the lowest common multiple of 217,765,901,297,645 is 12484738035.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
217 x 765 x 901 x 297 x 645 = 28652473790325
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
217 : 1, 7, 31, 217
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
901 : 1, 17, 53, 901
297 : 1, 3, 9, 11, 27, 33, 99, 297
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,765,901,297,645, is 1.
Now, the common factors can be found like this.
217:7x 31
765:3x 3x 5x 17
901:17x 53
297:3x 3x 3x 11
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 17 = 2295
Therefore, the value for common factors is 2295.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 28652473790325/(1x2295)
LCM = 28652473790325/2295
LCM = 12484738035
Thus, we can understand that the LCM of 217,765,901,297,645 is 12484738035.
